Designing Saga Orchestrators

In an Orchestration Saga, a dedicated service, called the Orchestrator, takes charge of managing the entire distributed transaction.

Think of it as a conductor in an orchestra. Instead of individual musicians (services) reacting to each other, the conductor (orchestrator) tells each musician when to play their part.

Orchestration offers several advantages, especially for complex business flows:

• Centralized Logic: All saga logic resides in one place, making it easier to understand and manage.
• Easier Changes: Modifying saga steps or adding new ones is simpler as changes are contained within the orchestrator.
• Clearer Debugging: It's easier to trace the flow of a transaction and pinpoint exactly where a failure occurred.
